Katherine Waterston cast opposite Eddie Redmayne in J.K. Rowling’s ‘Harry Potter’ spin-off

'Inherent Vice' actress will play an American witch named Porpentina in the Rowling-penned spin-off

Katherine Waterston has been cast opposite Eddie Redmayne in JK Rowling’s Harry Potter spin-off film Fantastic Beasts And Where To Find Them.

The actress, best known for her roles in Inherent Vice and Boardwalk Empire, will play an American witch named Porpentina who meets Redmayne’s character, Newt Scamander, author of a textbook used by Harry Potter at Hogwarts, when Scamander visits New York City.

Redmayne was cast earlier this month (June), with a Warner Bros. press release explaining: “Redmayne will play J.K. Rowling’s creation Newt Scamander, the Wizarding World’s preeminent magizoologist, who in his travels has encountered and documented a myriad of magical creatures, ultimately leading to his penning the Hogwarts School textbook Fantastic Beasts And Where To Find Them.”

Rowling has written the script for the spin-off film, which is set around 70 years before the Harry Potter saga begins. Warner Bros. has given the film a release date of November 18, 2016 and David Yates, who directed the final four Harry Potter films, in on board to direct.

Explaining the film’s premise when it was announced in 2013, Rowling said: “Although it will be set in the worldwide community of witches and wizards where I was so happy for 17 years, Fantastic Beasts And Where To Find Them is neither a prequel nor a sequel to the Harry Potter series, but an extension of the wizarding world. The laws and customs of the hidden magical society will be familiar to anyone who has read the Harry Potter books or seen the films, but Newt’s story will start in New York, 70 years before Harry’s gets underway.”
